•Research participants who fulfil diagnostic criteria for any type of dementia (e.g. Alzheimer Dementia, Frontotemporal Dementia (FTD), Diffuse Lewy Body Dementia (DLBD), Vascular Dementia (VAD), etc)
CDR =1.
•Known carriers of a presenilin 1 (PSEN1), presenilin 2 (PSEN2) or APP mutation associated with Autosomal Dominant AD or any other neurodegenerative disease.
•Prohibited or restricted concomitant medication as detailed in Section 10.1.7 in the protocol.
•Presence of any neurological, psychiatric or medical conditions associated with a long-term risk of significant cognitive impairment or dementia including but not limited to pre-manifest Huntington’s disease, multiple sclerosis, Parkinson’s disease, Down syndrome, active alcohol/drug abuse or major psychiatric disorders including current major depressive disorder, schizophrenia, schizoaffective or bipolar disorder. To quantify abuse is to define this as history of drug or alcohol abuse according to Diagnostic and Statistical Manual of Mental Disorders (5th Edition) (DSM-V) criteria within 6 months before screening or positive test result for alcohol and/or drugs of abuse at screening/admission.
•History of latent or active infection of one of the following infectious diseases at screening: Listeria infection, Histoplasma, Coccidioides, Paracoccidioides, Pneumocystis, nontuberculous mycobacteria, Blastomyces, Aspergillus, cytomegalovirus generalised or Herpes zoster infection
•Any cancer or history of cancer in the preceding 5 years (excluding cutaneous basal or squamous cell cancer resolved by excision).
•Any conditions that are clinically significant and may deem the participant’s participation in an investigational trial unsafe, e.g., symptomatic cardiovascular disease (including re-vascularisation procedures within the previous year), severe renal or hepatic failure, any clinically relevant abnormalities in blood parameters included in local routine assessments, severe loss of vision, hearing or communicative ability, conditions preventing co-operation or completing the required assessments in the trial, as judged by the Investigator.
•Any contraindications for PET/MRI scanning.
•Any contraindications for Lumbar Puncture.
•Any evidence of intracranial pathology which may affect cognition including but not limited to brain tumours (benign or malignant), aneurysm or arteriovenous malformations, territorial stroke (excluding smaller watershed strokes), history of or recovering haemorrhage (parenchymal or subdural), or obstructive hydrocephalus. Research participants with an MRI scan demonstrating markers of small vessel disease (e.g. white matter changes or lacunar infarcts) judged to be clinically insignificant, or microbleeds are allowed.
•Participation in a clinical trial with an Investigational Medicinal Product (IMP) in the last 30 days or 90 days in case of biologics.
•Diminished decision-making capacity that renders the individual not capable of consenting.
•Any other factors in the opinion of the Investigator that could contraindicate the participation of the research participant into this trial.
